Curse of the Black Widow is a 1977 American made-for-television horror film directed by Dan Curtis and starring Tony Franciosa, Donna Mills, Patty Duke, Vic Morrow and June Allyson. It originally aired on ABC on September 16, 1977 and was re-released in 1979 as Love Trap. Plot For the past four years, Los Angeles has been terrorized by a series of mysterious murders, in which several men have been found dead with huge puncture wounds in their chests. The latest happens when private detective Mark Higbie is visiting a bar. A dark-haired woman with a German accent needs help with her car, and one of Higbie's friends goes out to help her. The woman makes a pass at him, but is turned down. Minutes later, the man is found dead. Mark does some digging and finds out that Lieutenant Gully Conti, who is leading the investigation, knows who the culprit is, but is covering up details. He soon finds out why; all of the victims have had their bodily fluids sucked out of them, and the wounds are filled with spider venom. Each time, a mysterious woman named Valerie Steffan was in the area. Gully suspects that the twins, Leigh and Laura Lockwood, are somehow involved. Leigh hires Mark, concerned about the police focusing on her. It turns out that she dated all of the men who have died so far. Mark eventually gets in touch with a former bartender who saw one of the murders, who tells him that at least one man was killed by a man-sized black widow spider. Checking further, he finds out that Leigh and Laura's father died in a plane crash several years ago, and one of the girls was nearly bitten to death by spiders. Mark finds out that the plane landed in an old vineyard owned by the Lockwoods, and meets an aging Native American who found the girls. The Native American says that according to an old legend, some women are affected by an ancient curse passed through the female line. During the full moon, these women turn into giant spiders in times of stress, kill their victims, encase them in webbing and feed on them. These women have a red hourglass-shaped birthmark on their abdomens, similar to those found on black widow spiders. They are practically indestructible in spider form; the only thing that can kill them in that form
